Multiple route paths with same params

[juusaw]

It seems that using multiple paths with same route parameters within a route overwrites the parameters for some routes. This can be reproduced by defining a route like this:

const route = {
  path: ['/one/:parameter', '/two/:parameter'],
  action: ({ params }) => { console.log(params) }
}

When navigating to the former route, params seems to contain the key parameter but the value is undefined. The latter route works as expected, yielding a value for the parameter.

I tested the case with version 3.2.0 and 4.0.0.
